All Omada devices lost fixed IP addresses

Model: ER707-M2   TL-SG2428P   EAP670  
Hardware Version:
Firmware Version:

Controller: OC200

 

My entire network went offline and stopped responding. Then when it came back - all of the IP addresses changed, and I have 22 DHCP reservations. All of the devices have fixed IP addresses - controller IP changed, (3) EAP devices took different IP addresses, and it very much disrupted the functioning of the network for quite some time. I don't understand - the ER707-M2 has the DHCP reservations, did the controller come back up before the gateway was up? In that case there would be no DHCP server. How did this happen?

Also noticed a few devices not picking up their intended fixed IPs over the last 24hrs, both wired and wireless. Also using er707m2 (1.2.3), oc200 (5.14.32.56/2.17.6) and two eap670s Changing the fixed ips to outside the dhcp range and restarting the controller worked for some wireless clients but not one wired one my network just now.

ER707: 1.2.3 Build 20240822 Rel.52946

SG2428P: 5.20.5 Build 20241104 Rel.40492

EAP670s: 1.1.0 Build 20240829 Rel. 54375

 

I rebooted the EAP670s and the switch and many of the devices picked up the proper address now. But as an IT admin, this should never happen. The gateway should not be distributing assigned ip addresses to any device other than the mac specified.
